Upon seeing this, the Xuanmen Emperor couldn't help but sneer, his face full of disdain as he mocked, "Hmph! It's nothing but a show of mystery!"

But as soon as he finished speaking, he suddenly felt something strange. Looking down, he was horrified to find that his feet had begun to slowly dissipate, as if they had been swallowed up by some mysterious and powerful force.

Immediately afterwards, this strange phenomenon spread upwards rapidly. Before long, the legs, body, and even arms of the Xuanmen Emperor gradually became transparent, and it looked as if he was about to completely disappear from this world.

At the same time, he turned in horror to look at the other three emperors beside him, only to find that they were in the same terrible situation as him.

At that moment, the eyes of the four emperors seemed to be filled with endless fear. They trembled as they looked at the nine ancestors of the Yuan clan, and their bodies began to slowly dissipate from their feet upwards until they finally disappeared above their heads.

In the blink of an eye, these four emperors, who once dominated the world and wielded immense power, perished completely, their souls scattered and gone.

However, faced with such a tragic situation, the Ninth Ancestor of the Yuan Clan did not even glance at them. He turned his body indifferently and said coldly to the other side, "Remember in your next life, never oppose my Yuan Clan again!"

The words had barely left his lips when a deafening roar echoed through the heavens. In an instant, the entire world trembled violently, as if this vast and boundless realm was about to crumble.

Then, a shocking scene unfolded—a torrential downpour of crimson rain suddenly descended from the heavens and earth, with raindrops the size of beans pouring down, staining the earth red and soaking into people's hearts.

At the same time, a series of mournful cries echoed from the sky, like the wailing of ten thousand ghosts or the lamentations of vengeful spirits, seemingly expressing the most sincere and profound grief for the unfortunate demise of the four emperors.

The Great Emperor has fallen, and the world mourns!

At this moment, on the battlefield, whether they were the high and mighty emperors, the slightly inferior quasi-emperors, or even the many extraordinary saints, they were all utterly shocked by the terrifying scene before them, which resembled the end of the world.

The blood rain falling from the sky was like tears of blood shed by heaven, filling people with immense sorrow and despair.

"Your Majesty..."

Upon witnessing this scene, the people from the four major powers—the Divine Mystic Holy Land, the mysterious and unpredictable Xuanmen, the dreamlike Other Shore City, and the Immortal Sect—were all filled with grief and cried out the name of their respective emperors to the heavens.

Their cries mingled together, echoing between heaven and earth, lingering for a long time.

At this moment, the remaining True Dragon Clan Emperor, Wang Family Emperor, Tiancang Clan Emperor, and the heavily injured Golden-Winged Roc Emperor all turned their gazes toward the Yuan Clan's Ninth Ancestor, their eyes revealing deep fear.

It should be noted that just now, the Yuan Clan's Ninth Ancestor, with a single move, instantly killed the four Great Emperors like autumn leaves being swept away by the wind.

Such terrifying strength far exceeded everyone's understanding of the power that a fifth-tier Great Emperor could possess.

Faced with such a formidable enemy, the four remaining emperors were extremely anxious. They quickly used their supreme divine sense transmission technique to send a message to the Lord of the Underworld, who was far away on the other side of the battlefield: "Old ghost, do you really have to wait until all of us have perished before you reveal your final trump card?"

The Lord of the Underworld was startled after receiving the divine thoughts from the four Great Emperors.

He knew the situation was extremely critical, and if no action was taken, the consequences would be unimaginable. So, he made a decisive move, abruptly withdrawing from the intense battle. In a few flashes, he appeared beside the four emperors like a ghost.

However, the Ninth Ancestor of the Yuan Clan was not afraid at all when he saw this scene. Instead, he raised the corners of his mouth slightly and revealed a mocking smile. He sneered and said, "Oh? What, are you planning to fight me with your meager strength, or are you preparing for the final dance of ultimate sublimation?"

The Lord of the Underworld's already extremely gloomy face became even more twisted and ferocious due to the mockery of the Nine Ancestors of the Yuan Clan. His eyes, filled with rage, were fixed on these old fellows who had once looked down on him and the Netherworld. He roared through gritted teeth, "You bunch of old fools who don't know what's good for you! Your disdain for the Netherworld back then, and your failure to completely annihilate it, is the biggest mistake you've ever made! Today, I'll let you taste what true despair is!"

Upon hearing the Lord of the Underworld's harsh words, one of the nine ancestors of the Yuan Clan merely smiled contemptuously and replied dismissively, "Hmph! You arrogant fool, I'd like to see what your so-called despair looks like."

Just then, the Lord of the Underworld slowly stretched out a hand, and a jet-black bead emitting an eerie light appeared in his palm.

He gripped the bead tightly and squeezed it hard. With a crisp "crack," the seemingly hard, jet-black bead instantly turned into a pile of dust.

However, something unexpected happened. As the bead shattered, dark clouds suddenly filled the sky, and thunder and lightning roared incessantly.

Immediately afterwards, an extremely dense black aura of the underworld surged out from the clouds like a ferocious beast, spreading rapidly and covering the entire sky in the blink of an eye, plunging the world into darkness.

At the same time, three terrifying auras, so powerful they were chilling, suddenly erupted from the overwhelming aura of the underworld.

The power contained in these three auras far exceeded that of the Great Emperor level, and could even be said to be countless times stronger.

The moment they appeared, those powerful individuals whose strength had not yet reached the Quasi-Emperor level felt an irresistible pressure bearing down on them.

Their faces turned deathly pale, their bodies trembled uncontrollably, and then they all opened their mouths and spat out a mouthful of bright red blood.

Then, these powerful individuals seemed to have lost all their strength, collapsing limply to the ground, unable to move an inch.

Those powerful figures at the Quasi-Emperor level, whether ordinary Quasi-Emperor level experts or top-tier beings who have reached the ninth level of the Quasi-Emperor level, were all unable to withstand that extremely terrifying pressure at this moment.

Some of them knelt down on one knee, struggling to support themselves with their hands; others, unable to withstand the immense pressure, knelt down on both knees, struggling as if carrying a thousand-pound burden.

Just then, three figures suddenly appeared in the void like ghosts.

Compared to ordinary emperors, these three figures exuded an even greater aura of power. Their solemnity and reverence inspired awe and deterred any thought of offense. They were like high-ranking gods, looking down upon the insignificant beings beneath their feet, like ants.
